1 Specification of Letters Patent; Patented M31, 19, 1918.

Application filed September 13, 1916. Serial No. 119,893.

To all whom it may concern:

Beit known that I, THOMAS ,MILLWARD, a citizen of the United States, residing at San Francisco, in the county of San Fran cisco, State of California, have invented a new and useful Carbonating-Machine, of which the following is a specfication in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a machine for carbonating beverages and its object is to produce a machine which will use as little power as possible above that stored in the tanks from which the supply of water and CO under pressure is obtained and is an improvement upon the invention disclosed in Patent No. 1,177,531, granted to me March 28, 1916, in that the present invention dispenses with the snifi valve disclosed in that patent and provides improved operating mechanism.

Another object of the invention is to produce a machine which will be capable of carbonating and discharging a small quantity of water with each operation thereof, the machine being small enough to be adaptable to bars and candy stores where the water is drawn off as it is carbonated.

Another object of the invention is to re duce the number of valves used in the construction of the machine to a minimum thereby reducing the weight and cost of the completed machine.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof.

Figure 1 is an end view of the complete machine showing the water supply tank, the gas mixing tank and discharge spout,

Fig. 2 is a side elevation of the machine looking from the left of Fig. 1, s

Fig. 3 is a side elevation of the machine looking from the right of Fig. 1,

Fig. 4 is a plan view of the complete machine,

Fig. 5 is a vertical sectional view of one of the valves and the operating arm therefor, and

Fig. 6 is a vertical sectional view of the check valve.

The numeral 1 indicates the base upon which a cylinder 2 is formed, said cylinder having removable ends 3 and 4. The end 4 is provided with a central boss 5 forming a packing gland with suitable packing 'fixed bearing cap 10. The shaft 9 has two segment gears 11 and 12 mounted thereon at opposite ends of the bearing cap.

The segment gears are mounted to rotate with the shaft 9 as it is oscillated by means of the handle 13, said handlehaving bosses 14 and 15 connected therewith and rigidly connected with said shaft. The boss of the gear 11 has a notch therein with an inclined cam 16, while the gear 12 has a notch with an inclined cam 17 therein facing in the opposite direction from the cam 16. The boss 15 has a lug 18 which projects into the notch adjacent the inclined cam 16 and'the boss 14 has a lug 19 which projects into the notch adjacent the inclined cam 17.

Suitably secured to the cylinder 2 adjacent the center thereof are two arms 20 and 21. The arm 20 carries a double bell crank lever 23 having two arms 24 and 25. The arms 24 and 25 are provided with set screws 26, 27 for the purpose of opening the valves controlled thereby at the proper time as will be later explained. At its upper end the double bell crank lever 23 passes into a notch 28 on one end of the shaft 9. At the other end of the shaft 9 there is a notch 29 to receive the upper end of a bell crank lever 30, which has an arm 31 projecting over a valve 32 for the operation of said valve as will be later explained. The arm 31 is provided with a set screw 33 for the purpose of opening the valve 32 'at the proper time, the adjustment of said set screw providing the means for properly timing the opening of said valve.

The segment gears 11 and 12 are in mesh with two rack bars 36, 37 which are connected to a yoke 38, the latter in turn being connected to the piston rod 7.

The water supply is contained in a suitable receptacle 40 which has a pipe 41 leading therefrom. to a downwardly opening check valve 42. A pipe 43 connects the check valve 42 with a T 44from which T a pipe 45 extends to the downwardly opening valve 46 the branch 44 extending into the cylinder'2. Adjacent the valve 46 is a valve 47, and pipes 48, 49 extend from the two valves last, mentioned into the car bonating receptacle 50, the pipe 49 extending nearly to the bottom of said carbonat- 1 and is connected with a T 55, one branch of which 56 is connected with the cylinder head 3. From the other branch of the T a pipe 57 extends to the outlet valve 82, said valve having a spout 58 thereon to allow the escapeof liquid from the cylinder when achargeis to be withdrawn the efrom. The T 55 has a partition 55 to direct the incoming liquid into the cylinder instead of trapping the airy and gas in the pipe 57.

The operation ofthe carbonating machine is as follows: Assuming the tank 40 to be filled or partially filled with water the operating handle 13 is operated to draw a charge of water into, .the cylinder 2 by moving it to the right, Figs. 3 and 4. lVhen the handle is moved to the right, Figs. 8 and 4, the cam on the segment gear 11 will throw the handle so asto close both of the valves 46, 47 and at the same time the. valve 32 will be opened The movement of the handle continues until it assumes the. position shown in Fig. 3, thereby moving the piston to force any water in the cylinder out through the discharge pipe. As soon as the handle reaches the end of its throw it may he moved to the left (Fig. 3) whereupon the cam 17 will at once cause the handle to move laterally alongits axis or down Fig. 4, the movement of the shaft 9 closing the valve 32 and opening both of the valves 46 and 47 thereby equalizing the pressure at both ends of the cylinder 2 Since there is a downwardly opening check valve 42 below the tank 40 on the water supply pipe the water cannot be blown out of the cylinder. When the pressure has been equalized on both ends of the cylinder 2, the dead water therein may betrans-ferred to the charging cylinder easily by mov-ingthe handle and piston to the reverse position, asupply of charged w-ate 1 takingitsplate on the opposite side of the piston. When the handle is moved to the left hand position opposite to that shown in Fig. 3, the left hand'end of the cylinder has received its charge asabove mentioned and the handle may then be moved to the right to the position shown in Fig. 3. The first result; of the movement to the right will be to move the handle latera ly along its axis by the cam 16, see Fig. 4, the shaft 9 bearing on the bell crank lever 30 and lifting the lever 28 thereby closing both valves 46, 47, and opening the valve 32. As soon the handle starts to move to the right hand position Fig. 3, the valve 32 is opened, tl e air or gas trapped in the cylinder will be blown out and the handle may be moved to the position shown in Fig. 3 thereby delivering a charge of carhonated'water. The cycle of operations may be repeated as often desired;
